Abstract
Disclosed is a non-powered seawater pumping apparatus for reducing seawater intrusion in a land in which an aquifer with a seawater-fresh water boundary surface is formed. The seawater pumping apparatus includes a pumping pipe having two open end portions, a first end portion of the open end portions being positioned below a sea level and a second end portion being positioned below the seawater-fresh water boundary surface in the land, and a well disposed to surround a lateral surface of a land-buried portion of the pumping pipe, which is buried in the land, so as to space away the land-buried portion of the pumping pipe from the land. The pumping pipe is filled with seawater, and the well comprises a screen having a plurality of through holes formed along a circumference of the well at a lower end portion of the well.
